Piling Uxbridge

Classification of Piles Based on the Material and Piling Construction Method

There are two further classifications for primary piles; Displacement Piles and Non-displacement or Replacement piles. Piles that are driven to the ground and vertically or radially displace the soil are known as Displacement Piles. On the other hand, For Replacement Piles, the boring of the ground takes place, after which the soil is removed and the whole caused using the bore are filled with concrete to create a strong reliable base. A pre-cast concrete pile is also used in this method instead of filling it with concrete. When we talk about the material for piling construction, and then the installation process can be further classified as;

• Timber Piles
• Untreated
• Treated with Preservative
• Concrete Piles
• Pre-cast Piles
• Cast-in-place piles
• Steel Piles
• I-Section Piles
• Hollow Piles
• Composite Piles

Timber Piles

Timber piles placement take place under the water level. The duration of their life span is almost 30 years. These piles are available in two types of shape; rectangular and circular in 12 to 16 inch size or diameter. As compared to the top width the Timber piles’ length is 20 times larger.15 to 20 tons is the weight that usually these piles can bear easily, additional strength provision is also possible with the help of fish plates. This is possible by bolting fish plates at the sides of the Piles.

Advantages of Timber Piles

• You can easily find regular size timber pile
• These piles are more economical and affordable along with easy installation
• The possibility of damage in these piles is low
• Cutting of Timber Piles is possible and can be converted into any length to get a perfect fit after the installation, and are also easy to pull out, in case of such need

Disadvantages of Timber Piles

• It is hard to find the piles of longer length all the time
• If you are looking for short length, straight piles are difficult to obtain
• If the soil strata are not favourable or very bad it can become hard to drive the pile
• When it’s about the splicing of timber pile, it is not easy
• As end-bearing piles, timber and wooden piles are not favourable and suitable for use

When it comes to the durability of the timber piles, some measures are essential like the use of preservatives to treat the wooden piles.

Concrete Piles

Concrete piles can be further classified into two Pre-cast piles and Cast-in-place piles

Pre-cast Concrete Pile

If these piles are rectangular, they are cast in horizontal shape in pile bed, and used in vertical shape and the circular piles are cast. To prevent breakage during mobilization these piles are reinforced with steel, from the casting bed to the foundational location. The process of curing is necessarily performed after casting, generally, the curing period for Pre-cast concrete piles is 21-28 days.

Cast-in-Place Piles

The process of boring is used to cast these piles, to the desired depth. Then these are filled or deposited with the concrete and then the process of curing takes place. The construction of these piles takes place by driving a metallic shelf. This shelf which is filled with the concrete is either left with the concrete or while concrete is poured the shell is pulled out.

Both of these concrete pile classifications have some advantages and disadvantages, but all depends upon your use of them.
